The documentation around the vertex and mesh functions seems a little shy. I'm trying to directly manipulate to the vertices of an object... in my case a sphere. I'm trying something like:



My questions are -- am I using the lock/unlock properly (are they even needed) and more importantly, after I do this, how do I get the mesh associated with my original object? I don't see a dbMakeObjectFromMesh function.
Is this all just crazy talk?!

Thanks.

Yes and yes.

dbMakeObject(), or dbChangeMesh().

However, there may be a problem with what you are doing (or might not). When you make a mesh from an object, it will combine all of the existing limb meshes, with rotation and scaling, in to a single mesh.

An alternative is to manipulate the limbs in place using the dbLockVertexDataForLimb() function, but you'll need to manipulate the vertices for each limb.

Thanks for the reply and the warning. In my case I'm only using a simple, though large, sphere object/mesh (you guessed it.. a space game), so the limb thing isn't a problem... for now.
Thanks again!
